Quizplus · Accepted Answer

A correlation coefficient ranges from -1 to 1, where -1 indicates a perfect inverse correlation (as one variable goes up, the other goes down), 0 indicates no correlation, and 1 indicates a perfect positive correlation (as one variable goes up, the other also goes up). An absolute value of the correlation coefficient closer to 1 indicates a stronger correlation. Therefore, the correlation coefficient of .88 indicates a strong positive correlation between measured IQ at ages 8 and 10.
